Write a context-free grammar for arithmetic expressions consisting of non-negative binary integer numbers defined in Activity 1 and four operators, + (addition), -(subtraction), * (multiplication), and / (division). No precedence or associativity need to be considered in the grammar. In addition, no parentheses can be used in expressions. For example, (10 - 1) * 101 is not acceptable. The regular grammar you have obtained in Activity 1 should be included as part of your solution. Turn in your solution by the date when Section 12.2 is finished.
Transform the context-free grammar obtained in Activity 5 to a pushdown automaton using the algorithm in Section 12.2.2. Turn in your solution by the date when Section 12.3 is finished.
Write parsers for arithmetic expressions. Transform your grammar into a LL(1) grammar. You may need to do a left-factoring of common prefix of productions, and/or to remove any left-recursive productions in the grammar for aritmetic
expressions using the algorithm in Section 12.3.1. Then write a recursive-descent parser for the context-free grammar for arithmetic expressions using the algorithm in Section 12.3.1.
Turn in your solution by the date when Section 12.4 is finished.
Design and implement an AVL tree algorithm that searches a collection of documents. You will be provided with a set of 50 documents and a set of sample queries. First, you will process the documents and store their content (i.e. words / tokens) in..
